transmission system is used to connect interrupter and operating mechanism in high voltage circuit breaker

to do opening

closing. But the transmission system may also have a negative impact on the movement of transmission. In this paper

a certain type of CB is taken as the research object

the test results of mechanical characteristics are analyzed

and the matching relationship between transmission system and operating mechanism characteristics is discussed from a new perspective. By optimizing the matching between the two

the performance of circuit breaker isimproved

which can provide design reference for future design.
